Abstract:

The binary coded decimal of a number is selectively loaded into presettable counters. A switching means sequentially connects each of the binary levels of each of the digits comprising the number to an International Morse Code memory addressing a selected segment thereof. A binary counter sequentially addresses each of the bit locations of the selected memory segment thereby serially generating, in Internatonal Morse Code, the digit contained in the addressed memory segment. Upon completion of the code translation of a selected digit of the number, the switching means connects the binary levels of the counter containing the next lesser significant digit to the memory address and the binary counter is recycled. Means are included for selectively deleting the generation of leading zeros of the number and for selectively abbreviating the International Morse Code generation of certain digits comprising the number.
